This nonsense has to stop.
I think the coaching tree that produced
Nick Saban, Pat Hill, & Kirk Ferentz as well as 17 currently serving coordinators/assistants should get a little more credit than it deserves. I just read an article that 13 current HC in the NFL are from Belichick offshoots. I'll see if I can find it again.
Bill O'Brien was moderately good as a HC but a sucky GM. Al Groh was pretty good, too. Schwartz realized he was a crappy HC and went back to coordinating. He's killed it since leaving.
Judge inherited a shitshow as did Flores. Vrabel might turn out to be good. Time will tell if they suck or not.
His Sith Lords aren't being groomed to perform head coaching duties; they're performing their jobs as position coaches and coordinators. And a fare number of them go off and have good careers. Not everyone is going to be or wants to be a HC.
In 2018, 28 of 32 head coaches were tied to Parcels and Belichick.
For every Saban or Hill there will always be another Weis and Mangini. For every O'Brien or Groh there will be a Patricia and Crennel.
Parcells produced Bill & Payton but also some real clunkers, too, like Anthony Lynn and many others.
His tree is wide and deep but not every branch is lush. Some are friggin' missing, lol!
